Where in the world is oral cavity cancer most common?

Reviewed: 8 November 2026 By: Xiangpeng Liu, MD Topic: Oral Cavity Cancer Answer length: short, citable
Quick answer

Oral Cavity Cancer is not evenly distributed: the highest-burden regions are India, South-Central Asia (Bangladesh, Pakistan, Sri Lanka) and Papua New Guinea & Melanesia. In 2022 there were about 317,500 new oral cavity cancer cases (C02–C06) worldwide (male ASR 4.6 and female ASR 2.0 per 100,000; 41.9% of all lip/oral/pharyngeal cancers in 2022), with marked country-to-country variation driven by local exposures such as tobacco, areca nut, oncogenic viruses, ultraviolet radiation and occupational carcinogens.

In detail

The regional pattern matters clinically. A patient from India may present with a different risk-factor profile and a different stage distribution than a patient from a low-incidence country, which changes both the differential diagnosis and the pretreatment work-up.

All incidence figures on this site are age-standardised rates or absolute case counts from GLOBOCAN 2022 and its subsite analyses. They describe populations, not individual risk.

  • India: 143,759 new oral cancer cases and 79,979 deaths in 2022 — 10.2% of all Indian cancers, ASR 10.1/100,000. Men account for ~75% (male ASR 15.6). Tobacco and areca nut explain roughly 70–80% of cases.
  • South-Central Asia (Bangladesh, Pakistan, Sri Lanka): Oral cavity cancer makes up 59.8% of all lip/oral/pharyngeal cancers in the region. Male ASRs: Sri Lanka 12.4, Bangladesh 12.0, Pakistan 11.3; female ASRs: Bangladesh 6.4, Pakistan 5.9.
  • Papua New Guinea & Melanesia: The highest female oral cavity ASR worldwide (8.1/100,000) and male ASR 9.6, linked to areca nut and betel quid chewing.
  • Southern Africa & parts of Western Africa: Oral cavity represents 48.8% of the lip/oral/pharyngeal burden in Southern Africa, with elevated male rates.
  • Southern & Eastern Europe: Oral cavity accounts for 38.8% of Southern European and 14.1% of Eastern European lip/oral/pharyngeal cancers, largely tobacco- and alcohol-related.
  • United States: About 58,000 Americans are diagnosed with oral cancer each year with around 12,000 deaths; substantially lower ASR than South Asia.
